To all 107mm may concern.-

Be it known that I, THOMAS M. DILLINGER, a citizen of the United States,residing at Portland in the county of Multnomah and State of Oregon,have invented a new and useful Improvement in Leather Cutters, of whichthe following is a specification, reference being had to theaccompanying drawings. 9

My invention relates to leather cutting de vices as a class.

The object of my invention is to provide a manual cutting device with anadjustable knife and a spring clamp to press the material to position,adapted to cut leather or other material of varying thickness in stripsof desired widths. These objects, as well as other advantages, I attainby the construction, combination and arrangement of parts illustrated inthe accompanying drawings which form a part hereof.

Fig. I is a top plan view of the device with a strip of material incutting position.

Fig. II is a side elevation of same on the cutting side. i

Fig. III is a front elevation.

Fig. IV is a detail view of locking key.

Fig. V is a detail view of spring guide for material.

Fig. VI is a plan view of grip-holder for holding the knife while beingsharpened.

Like characters refer to like parts in the views.

The device has a metal frame 7 rigidly secured to a handle 8 which has acurved side support 9. The frame has a transverse rectangular opening 10through its forward part, a vertical guide 11 on its upper part, athreaded locking pin or set screw 12 mounted in a vertical threadedaperture 13 in the upper part of the frame. extending downwardly to theopening 10. The pin 12 has a longitudinal recess 14 in its outer part,with a series of faces in said recess, adapted to receive and engage akey 15 provided with corresponding faces about it and near one In theforward end of the, frame are a like horizontal aperture 16, ex-

end thereof.

tending to the opening 10, and a pin 17 with opening 18. A cutting knifecarrler 19 has a flat rectangular plate slidable through and within theframe 7, with an integral block 20 on one end, having a vertical,transverse opening 21 through the same. The block 20 has in its forwardpart a horizontal aperture 22, extending to the opening 211 This open--I ing and pin 23'are similar to those' -in the frame. A vertical cuttingknife 24: is placed within the block opening 21. A flat holding piece 25may be employed to" engagethe knife on one side and receive the engagingpin orset screw 28 on its opposing side. The knife'is retainedin'desiredposition pressed between the piece 25 and the opposite interior face ofthe plock 20 in its opening 21. A curved spring clamp 26 is rigidlysecured at one end upon the upper surface of the handle 7. The clamp 26extends outwardly and downwardly with a rearwardly curving. free end 27formed to rest upon material passing over the upper. surface of theblock 20 and opposite and transversely to the'cutting edge of the knife24. Material, for example, a leather strip 28 is shown in position forcutting and partly cut. In Fig. V is shown another spring clamp similarto the clamp 26 but with'a larger free endwhich may be required formaterial ofgreater width. A. grip holder 29 may be provided to hold theknife, such as here used, when the same "is to besharpened. It consistsof a handle with a split 30 from one end, in which to insert the knife24:, and fastening means 31 to secure it in place. The setting pin orscrew 12 is positioned to act as a pivot for the carrier 19 in a mannerto allow a radial movement of its outer end carrying the knife. Thesetting pin 17 is positioned. to engage the edge of the carrier betweenthe position of the pivotal pin 12 and knife 24 and allow the carrier tobe moved radially is placed in vertical position between 'the face ofthe interior of theblock 20a'nd the piece 25, engaging the opposingsurface of the knife, the key isagain used to drive the pin 23 againstthe piece 25 and the knifeis secured in a desired position within theblock 20. The carrier 19 is then inserted in the frame opening 21 untila space of the desired width of material to be cut is attained betweenthe cutting edge of the knife to adjust the carrier and the opposingface of the frame and its guide 11. The pin 12 is then driven againstthe u aner surface of the carrier 19 to secure it in t e position towhich it is set. The pin 17 is driven against the outer edge of thecarrier 19 to adjust and secure it, and to provide a parallel alignmentbetween the face of the guide 11 and cutting edge ofthe knife. 4

Both pins are operated as he required to this position and secure itthere rigidly. It is well known that in sharpening a knife of the kinddescribed, a bevelled cutting edge may he made which is not central withthe body of the knife. It is therefore necessary to adjust the cuttinged e itself into a path of travel havi plane v parallel with of theopposing guide face. It is for this reason that the pin 12 is arrangedto act as a pivot and he carrier is first set forward beyond where itshould be and then a careful adjustment is made by forcing thecarrierirearwardly by the pin 17 until the cutting edge of the knife isin the desired position a stated. This fine adjustment is highlyessential in cutting such narrow strips as lacing, used for belts andthe like. It is assumed that the outer or side edge of the leather iscut evenly, and this edge is inserted against the guide 11 with the endedge against the cutting edge of the knife 24, the clamp 26 having itsend. 27 resting upon the upper surface of the leather. The handle 8 isgrasped firmly with a thumb upon'the clamp 26 which is depressedsufficiently to cause the leather to feed horizontally over the blocksurface against the knife. The part of the leather lapping beyond theknife is held rigidly in the other hand, while the hand grasping thehandle draws the device forward with the knife cuttingfrom the materiala strip of predetermined width. This operation is repeated as often asrequired. It is obvious that the knife may be set to cut material of avery narrow width or of greater widths and insure extreme accuracy inthe cutting so that opposing cut edges are in parallel alignment. Itwill also be observed that material, which is very thin or ofconsiderable thickness, may be easily drawn over the support and kept ina horizontal plane on the carrier block by proper pressure on the springclamp. While there are other cutters intended to perform like cutting, I

'contendthat none has therein the combinations of parts. or certainparts which my device has, to accomplish the knife adjustment, feed,smoothness and accuracy of operation here shown. My device is extremelysimple, economical in construction and easily and quickly. operatedmanually. it is in these respects, as well as others, d'stinctly new anduseful.

I claim:

1. in a cutting device, the combination of, a frame having a transversehorizontal opening and a vertical guide face, a knife can ier extendingthrough and slidable in said frame opening,.the carrier having avertical knife secured in same, a vertical set pin positioned in the.frame to allow it to engage the carrier beyond the guide face and act asa pivot for the carrier. and a horizontal set pin positioned in theframe to allow it to engage the edge of the carrier and move sameradially until the cutting edge of the knife is arranged along a path oftravel in parallel alignment with the opposing guide face, and the twopins to secure the ca rier rigidly in such position.

2. in a cutting device, the combination of. a frame provided withhorizontal opening through it, a vertical guide face and vertical andhorizontal setting pins movable in the frame into and out of its saidopening, with a carrier slidable within said opening and provided withvertical cutting knife and mean to secure the cutting knife therein,said carrier and frame being arranged to allow the carrier to beadjusted with the knife cutt edge in parallel alignment with the frameguide face and there secured by s id frame pins, also with a springclamp ri idly secured at one end and having its free end adjustabledownwardly upon mate rial passing over the surface of the carrier towardthe cutting edge of the knife.

3. ln a cutting device, the combination of, a frame provided with ahorizontal opening through it, a vertical guide face and vertical andhorizontal settingpiusmovable in the frame into and out of its saidopening, with a carrier slidable within said frame opening provided witha vertical cutting knife and means to secure the cutting knife there in.said carrier and frame being arranged to allow the carrier to be Listedwith the knife cutting edge in parallel alignment with l.e frame guideface and there secured by aid frame pins, also with a spring clamprigidly secured at end and having its free end ad ustable downwardlyupon material passing over the surface of the carrier toward the cuttingedge of the knife, and a curved support adj accnt to the carrierpositioned to support material being fed upon the carrier toward thecutting edge of the knife. ,1
